Inconel HX®, also known as Hastelloy X® is a nickel- chromium- iron- molybdenum alloy with great resistance to oxidation. The alloy’s oxidation resistance is outstanding up to 2200º F. For hot forming, the alloy should be heated to a starting temperature of 2150°F (1175°C). Inconel HX® can be welded by metal arc, gas-tungsten- arc, gas-metal-arc, and submerged arc processes.
